We are adopting a new airworthiness directive (AD) for certain CFE Company (CFE) turbofan engines. This AD was prompted by a quality escape for high-pressure compressor (HPC) impellers made from forgings with nonconforming material grain size. This AD requires removal of the HPC impeller. We are issuing this AD to correct the unsafe condition on these products.

Airworthiness Directives; CFE Company Turbofan Engines

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: We are adopting a new airworthiness directive (AD) for certain 
CFE Company (CFE) turbofan engines. This AD was prompted by a quality

HPC impeller. We are issuing this AD to correct the unsafe condition on 
these products.

DATES: This AD is effective May 31, 2017.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of May 31, 
2017.

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 by adding an AD that would apply to certain CFE CFE738-1-1B 
model turbofan engines with HPC impeller, part number (P/N) 6079T77P07 
or P/N 6079T77P09, installed. The NPRM published in the Federal 
Register on January 3, 2017 (82 FR 52). The NPRM was prompted by a 
quality escape for HPC impellers made from forgings with nonconforming 
material grain size. The NPRM proposed to require removal of the HPC 
impeller. We are issuing this AD to correct the unsafe condition on 
these products.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM (82 FR 52, January 3, 
2017) or on the determination of the cost to the public.

Conclusion

    We reviewed the relevant data and determined that air safety and 
the public interest require adopting this AD as proposed.

Related Service Information Under 1 CFR Part 51

    We reviewed CFE Service Bulletin (SB) CFE738-72-8080, Revision 0, 
dated August 18, 2016. The SB describes procedures for replacing 
specific serial numbered HPC impellers, P/N 6079T77P07 or P/N 
6079T77P09. This service information is reasonably available because 
the interested parties have access to it through their normal course of 
business or by the means identified in the ADDRESSES section.

Costs of Compliance

    We estimate that this AD affects 176 engines installed on airplanes 
of U.S. registry.
    We estimate the following costs to comply with this AD:

----------------------------------------------------------------------------------------------------------------

Authority for This Rulemaking

    Title 49 of the United States Code specifies the FAA's authority to 
issue rules on aviation safety. Subtitle I, section 106, describes the 
authority of the FAA Administrator. Subtitle VII: Aviation Programs, 
describes in more detail the scope of the Agency's authority.
    We are issuing this rulemaking under the authority described in 
Subtitle VII, Part A, Subpart III, Section 44701: ``General 
requirements.'' Under that section, Congress charges the FAA with 
promoting safe flight of civil aircraft in air commerce by prescribing 
regulations for practices, methods, and procedures the Administrator 
finds necessary for safety in air commerce. This regulation is within 
the scope of that authority because it addresses an unsafe condition 
that is likely to exist or develop on products identified in this 
rulemaking action.

Regulatory Findings

    This AD will not have federalism implications under Executive Order 
13132. This AD will not have a substantial direct effect on the States, 
on the relationship between the national government and the States, or 
on the distribution of power and responsibilities among the various 
levels of government.
    For the reasons discussed above, I certify that this AD:
    (1) Is not a ``significant regulatory action'' under Executive 
Order 12866,
    (2) Is not a ``significant rule'' under DOT Regulatory Policies and 
Procedures (44 FR 11034, February 26, 1979),
    (3) Will not affect intrastate aviation in Alaska, and
    (4) Will not have a significant economic impact, positive or 
negative, on a substantial number of small entities under the criteria 
of the Regulatory Flexibility Act.

List of Subjects in 14 CFR Part 39

reference, Safety.

Adoption of the Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA amends 14 CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES

2. The FAA amends Sec.  39.13 by adding the following new airworthiness 
directive (AD):

2017-08-08 CFE Company: Amendment 39-18857; Docket No. FAA-2016-
9380; Directorate Identifier 2016-NE-21-AD.

(a) Effective Date

    This AD is effective May 31, 2017.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to CFE Company (CFE) CFE738-1-1B model turbofan 
engines with a high-pressure compressor (HPC) impeller, part number 
(P/N) 6079T77P07 or P/N 6079T77P09, with a serial number listed in 
CFE Service Bulletin (SB) CFE738-72-8080, Revision 0, dated August 
18, 2016, installed.

(d) Subject

    Joint Aircraft System Component (JASC) 7230, Turbine Engine 
Compressor Section.

(e) Unsafe Condition

    This AD was prompted by a quality escape for HPC impellers made 
from forgings with nonconforming material grain size. We are issuing 
this AD to prevent uncontained failure of the HPC impeller, damage 
to the engine, and damage to the airplane.

(f) Compliance

    Comply with this AD within the compliance times specified, 
unless already done.

(g) Required Action

    Remove all affected HPC impellers from service at the next 
piece-part exposure and replace with a part eligible for 
installation.

(h) Definition

    For the purposes of this AD, ``piece-part exposure'' is defined 
as separation of the impeller from the compressor rotor assembly.

(i) Alternative Methods of Compliance (AMOCs)
